IMPROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letters Patent and making Dart of the same HOM- 'To all whom it may concern:V

Beit known that we,M`ART1N GAY WOOD and JOHN CAYwooD, of the county of Peoria, and State of lllinois, have invented a new and useful Improvement in Snlky-Cultivators; and we do hereby declare that thefollowing is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, lnaking a part of Athis specification, in which- Figure 1 is a perspective view.

Figure 12 is a section of shifting-block.

VFigure 13 is a view of inside of shifting-block.

Figure 14 is a view of swivcl-clevis on tie-bar.

Like letters in the figures of the drawings indicate like parts.

This is a sulky-cultivator, or one in which the driver is seated. Like the common machines of this kind, there are two side or seat-bars, B B, each about six and one-half feet long and two by two and one-half in depth, and supported at their centres on the axle-tree A, where they are fastened by set-screws in the gaugeblocks m m.

The forward ends of bars B B have bolted to their under sides the metal gauge-block Z l, from which the iron brace-posts y depend, and through which 4blocks the iron bar or guide, to which are attached 'the braceposts y of the inner plows, passes..

To the rear ends of. said bars B B, the seat D is suspended on the long staple under the bars, which staple allowsthe seat to be slid backward or forward to balance the neck-draught.

There are four adjustable shovels to this machine.

There is one plow under each seat-bar, supported by the beam a, which beam is suspendedby bolt through eyel at lower end of brace-post y, coming from under side of beam-gauge block l.

These beams are two inches wide by one-half inch thick, if of iron; if of wood, about two by two and one-half inches, and from ve feet six inches to six feet long, and bending downward in an arc of a circle,

to rear end of which curved part are fastened the shovels G.

The rear part of the beam n rises and falls in the slot of the adj usting-bar l) b, which bar is, in shape, a tuning-fork, the handle being bolted through seatbeam' B B perpemlicularly, and fastened on top with nut equidistant betweenaxle and seat.

The latter bar l) b carries between its lower extremities, allowing it to freely turn, a quadrant-shaped block,- of iron or wood, C, by which the plow is raised or lowered.

The adjusting-bar. is about fifteen inches long, and is made of either wood or iron, and of sufcient strength to act as slot for plow-beam.

The block for raising beam turns on the pin or bolt ruiming through lower ond of said bar l) l), and so made as to graduate depth of shovel by a range of three inches.

The same bolt also passes through eye iu a lever about twelve inches long, (of iron,) and iive-eighths of an inch thick, placed alongside of said plow-beam, and has its forward end bent at right angles and passes under said beam n, its rear end being curved the reverse way, to.present a hold tothe drivers foot in raising the plow, when necessary.

To lower part of cinve of beam uis fastened the apparatus, figs. 8 and 9, for adjusting a setting-shovel. The point of shovel is about two feet below horizontal part of beam.

The shovel is riveted to the iron draught-gauge q, fig. 9, of cast-iron, about five inches long by three inches wide, and three-burths of an inch thick, having projecting jaws s, containing slots on each jaw,

.and with an eye, t, near lower extremity.

The eye is received within the jaws of the shiftingblock u., fig. 8, and secured byholt.

rlhe block u is of cast-iron, andrhollowed down to within one-quarter of an inch of its oiter surface, and has two slots running transversely, to receive two bolts o c, passing thence through curve of plow-beam, and to enable shovel to be set either to right or left, if required. Said slots are two and one-half inches apart, corresponding with holes in plow-beam, a bolt to each hole.

In setting shovel to required inclination, the bolt passing through the slots in jaws s of draught-gauge, and through the shitting-block u, is loosened, by which means the incline of shovel is made, and then tightened at the required angle, the block u hinging on the eye and bolt at t, iig. 9.

The inside shovels are set in same manner, and are Aone foot in advance of the others; and their beams are of the sameA shape and materials, but shorter, except ing the addition of the staple p p, projecting from and parallel 'to side of beam, so as to allow the passage through it of the arm of crank b, used in lifting beam when shovelsare raised.

This arm b of crank is furnished with the liftergauge fr, a metal block, having therein a set-screw rt a.

The forward ends oi' inside beams are held by the s\ 'iv'el-elevis at lower end oi' brace-posts jj, which posts are further braced by au iron rod of three-quarters of an inch in diameter, welded to lower end of said braceposts, and curving backward and upward through the gauge-block k.

The swivel or clevis-block c c, g. 6, nas an eye in its forward end for pinning to plow-beam, and plays on the lower end of brace-post, by means ol' hole cast therein, to allow lateral motion to beam.

The gauge-blocks k 7c are oi' cast-iron, eightiinehes long, two and one-half inches wide, and two inches in depth, cast with an ob'lon g mortise transversely through them, three-quarters oi'an inch wide and two inches long, through which the metal bar orguide supporting plowbeams passes. Itis two inches wide and one-half inch thick.

Between said block 7s and upper surface of metal guide C are the gibs d d, as also ih the blocks l l, under bars B B, on side of machine.

All the "gauge-blocks are fitted with set-screws. The blocks l Z, under the side-bars B B, receive saniein a shoe east in upper side of block.

The inside plows are guided and raised with the wooden leverg` running beneath the s\\'ivel-elevis j, on theltie-bar ,ofiron,aboutltln'ee-eighths by tl :ree-fourths inch width by two feet length, and pierced at theilattened ends with three holes, at which point the bar is fastened to the angle of the cranks (l d by set-scre\vs.

The cranks D l) stand perpendicularly when plowing, and support the beams, as before described, and are bent at upper end forward, forming a horizontal arm about nine inches long, and are ther: bent downward,

and turn to right or left, or up and down, in the crankboxes e e. 'lhe lower 4arm of crank is twoi'eet long, and oi' three-lourths inch iron rod, and passes through the iron gauge-block, before described.

llhe lever by which the tie-bar, cranks, and beams are raised is about three feet long, its fuleruin being the swivel-clevis on the tongue E.

It has a metal plate screwed to its upper surface,

projecting a little beyond edge of it, by which to hitch l lever to the bent hook Il., bolted to the axle-tree A.

Thefhook is bent like a Siphon, its longest arm being bolted to axle-tree, and allowing lever y to pass freely beneath the short arm or hook.

The swivehclevis j, on tie-bar, has a roller above the lever, allowing it easily to slide over the lever, when latter is raised.

The crank-box e is attachedto the jaws of gaugeblock ff by pin, 5, allowing of a vertical semieircular motion to cranks.

Thecblockffis attached to axle-tree by means4 of slot ruiming horizontally through it, by which itis adjusted on the. axle-tree in gauging of' plow F.

The operation oi' the machine is this:

Ongoing to plow, the centre plows are lowered,`by means of lever g and cranks b l), ofi' the hook h. The side plows are lowered by means ofthe fooiflevers o o. The gauge-blocks lt It', l Z, regulate width of furrows, and the inner plows are guided, in case of crooked corn-rows, by the lever g the inclination of shovels, by the devices behind the shovels, and the depth of plow by means of the gauges 11, on cranks, and the blocks c e, in the adj usting-bars b b b b.

Advantages.

rlhe facility of setting plows at any distance apart on -the guide-bar, which cannot be done on common plows oi' this kind. Also, the double motion of lifting and dodging by one eontrivance. rlhe facility of raising or lowering inner plows and outer plows, and also of setting the inclination of plow to horizon, and oi' setting same obliqnely by one contrivance of gaugedraughts q and sliil'ting-bocks il.

Having thus fully described our invention,

lVhat we claim therein as new, and desire to seciu'e by Letters Patent, is-

l. Beams n. n, slotted bars 7) b 'b b, brace-posts A1/y, gauge-blocks l slotted guides m. mi, foot-levers o 0, and swivel-clevises c c, all constructed and operated substantially in the "n'1anner and for the purpose as herein set forth.

2. Beam-gauge blocks l.: 7., gibs (Ld, braec-postsjj, and beamst' i', in combination with cranks b I; and crank-boxes f f, cross-bar a, lever y, and hook 71,' all when constructed, and arranged, and operated in the manner and for the purpose as herein set forth.

3. Providing the shovel with a draught-gauge '(1, and con'ibining therewith a sluiting-block, u, for adjusting the shovel, snbstantiallyas set forth.

As evidence' that we claini the ibregoing, we have hereunto set our hands, in the presence ci' two witnesses.
